Make controlled volume that a kind of electrical equipment of predetermined Spline smoothing occur in output circuit.Relay is widely used in the control of secondary device
In loop, for safeguard protection, change-over circuit, automatically adjust and power monitoring etc..It is big in hydroelectric power plant's secondary device
Amount is using relay, it is necessary to carry out periodic check, it is ensured that relay status is normal.
A kind of relay checking method of generally use at present：Relay protection is coordinated to survey using the relay base of same model
Examination instrument is verified.Relay checking inspection project includes：Relay coil directly hinders, actuating of relay voltage, and relay returns
Whether voltage, relay normally open contact, normally closed contact action are normal.In the flow of verification relay at present, busy relay
Operation voltage, return voltage, drop-off to pick-up ratio etc. are measured automatically by relay-protection tester.But relay-protection tester
A contact of relay can only be verified every time, but in general, the number of connections of relay is more, if only verified wherein
One contact, then it cannot be guaranteed that other contact reliabilities.Therefore, it is necessary to verify whole contacts of relay.It is but if complete
Portion verifies all contacts of relay, then needs that wiring is varied multiple times and relay-protection tester dependence test function setting could be real
It is existing, wiring is repeated in whole process and sets work to take considerable time and bring security risk.The administrative equipment of automatic class is various,
In addition more outer station overhauling project is accepted, causes automatic teams and groups structure of personnel in short supply, so how in terms of relay checking
Improving efficiency, reduction workload and working time needs automatic crewmember to go to solve, and actually needs one kind can be just
Take and verify the device for checking electric relay of efficiency high.
So on the basis of the existing test equipment that can be utilized, a kind of reduction traditional relay verifying work is designed
Amount and working time and the servicing unit that can complete relay complete verification project has very strong realistic meaning.

In insertion platform of the present invention and measuring loop；Top is special cellular type, according to the relay of different voltage class different models
Corresponding base can be flexibly selected, so can be with the convenient and swift verifying work realized to a variety of relays.
The present invention coordinates relay-protection tester application method using portable relay checking platform, and specific steps are such as
Under：
Suitable electric protection tester voltage output end will be selected to be connected with portable relay checking platform first, so
The relay of required verification is inserted into corresponding relay base afterwards, selecting switch is got into corresponding type.Preparation is carried out
Afterwards, start verification platform, with the straight resistance of resistance measuring module measuring relay, the straight resistance of meter relay, then enable contact
Converted measurement module, now normally closed contact indicator lamp is bright, and normal opened contact indicator lamp does not work, with relay-protection tester to relay
Device coil is stepped up voltage, until normal opened contact indicator lamp is bright, and normally closed contact does not work, operation of recording magnitude of voltage；Finally by
Step reduces voltage, until normally closed contact indicator lamp is bright, and normal opened contact indicator lamp does not work, and return voltage value is recorded, if herein
The conversion of process normally-open normally-close contact indicator lamp is abnormal, then it is a problem contact to illustrate its corresponding contact, records the problem and connects
Point, so far single verifying work terminate.
The present invention principle be：It is assumed that relay to be verified is direct current 24V relays, include 4 pairs of normally-open normally-close contacts.
Base corresponding to first step selection, is inserted into direct current 24V basal seat areas 11 corresponding to platform, then by relay inserted base；
Relay-protection tester 3 is connected by second step with this platform, and selecting switch 4 is put at direct current 24V, to this platform and relay protection
It is electric on tester 3；3rd step presses platform start button 5, then presses the progress relay coil of resistance measurement button 6 and directly hinders measurement simultaneously
Record, after record, press resistance measurement button 6 and exit straight resistance measurement；4th step presses contact converted measurement button 7 and carries out coil
24 powered back contact change over condition measurements, now coil 24 is also no powered, and LED status is four normally closed contact indicator lamps
(BL1, BL2, BL3, BL4 are bright, and (KL1, KL2, KL3, KL4's four normal opened contact indicator lamps go out.Then in relay-protection tester
Upper selection direct current output, step-length set 0.1V, start to step up voltage from 0, the situation of change of viewing lamp 18, work as indicator lamp
The 18 four normally closed contact indicator lamps that change go out, and when four normal opened contact indicator lamps are bright, now magnitude of voltage, the value are record
Actuating of relay voltage；Finally start progressively small voltage, the situation of change of viewing lamp 18, when indicator lamp 18 changes four
Individual normally closed contact indicator lamp is bright, and when four normal opened contact indicator lamps go out, now magnitude of voltage, the value are that relay returns to electricity to record
Pressure.In the 4th step, if which docking point indicator lamp 18 changes without by the above situation, illustrate that contact dress changes to exist and ask
Topic, it is problem contact to record the contact.
The advantage of the invention is that：1 verification efficiency high.2 rapid verification whole contacts and straight resistance measure.3 is quick accurate fixed
Position failure contact.4 reduce verification personnel labor intensity.5 strong environmental adaptabilities.
In a word, a kind of portable relay checking platform of the present invention, including it is sequentially connected what is connect with relay-protection tester
Selecting switch, three groups of fuse wires and direct current 24V basal seat areas connected respectively, alternating current 220V basal seat area, direct current
220V basal seat areas.Also include platform power module, the resistance measuring module of relay coil both sides is connected to by base, is passed through
Base is connected to the contact converted measurement module of each contact of relay coil.The present invention is with contact indicator lamp as judging contact turn
Change and whether fine or not foundation, meet each model relay of various voltage class using all types of special purpose relay bases
The needs of verification, directly hindered using digital display ohmmeter direct measurement relay.The present invention is solved and verified present in prior art
Efficiency is low, can not rapid verification whole contact and straight resistance measurement, can not to be quickly accurately positioned failure contact, staff's work strong
Spend the problem of big.
More than, only presently preferred embodiments of the present invention, the practical range of the present invention is not limited only to, it is all according to the scope of the invention
The equivalence changes done of content and modification, all should be the technology category of the present invention.
